Too often, artists begin to perceive their work as a product of their own intellect. We forget that the mind is the great deceiver. That creativity is, in fact, a gift entrusted to the artist.
Suddenly and inevitably, the work becomes more about ego and less about art itself. This is the most common pitfall for artists. Our work suffers.
If it goes on too long unchecked, the artist transforms into the ego maniac. Which is, of course, the greatest tragedy in art. Our world suffers.
